[PAPINIANUS libro primo definitionum. ] §12.1.37.prCum ad praesens tempus condicio confertur, stipulatio non suspenditur et, si condicio uera sit, stipulatio tenet, quamuis tenere contrahentes condicionem ignorent, ueluti 'si rex Parthorum uiuit, centum mihi dari spondes?' eadem sunt et cum in praeteritum condicio confertur.
[PAPINIANUS, from the first book of Definitions.] When a condition is referred to the present time, the stipulation is not suspended, and if the condition is true, the stipulation is valid, even though the contracting parties, being ignorant of the condition, do not know that it is valid; for example, "If the king of the Parthians is alive, do you promise that one hundred shall be given to me?" The same rules apply also when a condition is referred to the past.
